Hi Sean,

Is it an Alko hitch? Just google "alko hitch pads". See also here... http://www.al-ko.co.uk/pages_faqs/friction-pads.html

Alko reckon the pads should last about 33k miles and they cost about £30-50. You could change them but another way is to try roughing up their faces and the towball with fine emery paper - that used to stop the squeeks for me.

Lovely Damascus barrel. (Who needs two barrels at a clay shoot anyway?)

Jon

TBH I have imperial machines and had no problems following Harold's plans but you could always ask Harold himself?....

For through dovetails, can you not cut two sides at once if they're that thin, or perhaps use a scrap backing piece to make up the thickness to the minimum?

Usually the problem is getting the capacity to handle thick enough timber.

Jon

To save changing to a saucer wheel on the Quorn you can also produce the gashes with a cut-off wheel in a Dremel.

Jon

Any good? **LINK**

Jon

Sugru? Not cheap but would do the job I think.

Thank you all for the suggestions and thank you Frances for recommending Midland Abrasives.

Harold was very kind to give me the benefit of his experience too and also suggested Midland Abrasives. He also added his ok to the idea of smaller wheels.

Frances, I really like the idea of powering the spindle from the lathe - thank you for the tip. Did you support the grinder body in any way or just leave it floating?

Many thanks and regards

Jon

Just found these wheels at a good price...

Has anyone used Midland Abrasives before?

Many thanks

Jon

Sorry, I should have mentioned that my tooling is all HSS and so I'd prefer AlOx, or perhaps at a stretch CBN, rather than diamond.

Jon

Hello All,

I'm looking for one of each 60-grit open cup and saucer wheels at a reasonable price as well as some advice please.

My grinder is a cheap double ended 125mm unit to be used with Harold Hall's advanced rest and so I think could reasonably accommodate either 100 or 125mm wheels. Which size would you recommend and where would you get them from?

Any advice gratefully received - Many thanks

Jon

There's a video of one in-use here... **LINK**

It looks as if your positioning is pretty close according to that.

Jon

Thanks Brian, will do.

Finished my Harold Hall Advanced grinding rest last night.

Just some fettling left to do and then it's on with the accessories.

I have a cheap grinder to convert but it also needs some work. So, it'll be a while before I'm sharpening end-mills.

Jon

Heat and oil works but probably more faff.

I recently tried Casey Super Blue from these folks... **LINK**

Usual caveats - just a satisfied customer.

Scrupulously clean and degreased (hot water and washing up liquid), and wearing disposable gloves, followed by a couple of wipes over from the bottle - no real need to dip it IMHO. Followed by rinse in hot water and then dried and oiled.

Not the greatest photo but the knurl and dial indicator holder here were done this way.

...but the headline "Reasonable decision by engineers prevents accident that may have caused death of crew and spectators" isn't going to sell many papers

Really? I can accept your differing view but the definition neither says or implies liberal thought means agreeing with all of the opinions of others - just respecting and accepting.

Jon

"Health and Safety shoots down entire RAF" - The headline did make me laugh though. I'm not sure whether it was Ady's or a quoted one.

Last time I checked, merlin's were not powering our front line RAF defence capability

Interesting response but even Myford adopted M5, in place of 2BA and M6 and M8 capscrews in place of 1/4 and 5/16 BSF, for cost reasons before the 7 series lathes ended official production.

Personally I don't see the problem and happily mix metric and imperial especially for clamping on my old entirely imperial ML7 and all-UNC imperial mill.

Sorry, missed that
